Human Growth and Development Final Exam
1. Which state of arousal is considered the most fleeting?
- A. Regular sleep
- B. REM sleep
- C. Drowsiness
- D. Quiet alertness
Correct answer: D
Rationale: Quiet alertness is indeed the most fleeting state of arousal. This state is characterized by a newborn infant being awake, calm, and attentive, but it is short-lived and transitions quickly to other states of arousal. Regular sleep, REM sleep, and drowsiness are not considered as brief and transitional as quiet alertness in newborn infants.
2. Currently, the most widely used potent teratogen is __________.
- A. aspirin
- B. diethylstilbestrol (DES)
- C. thalidomide
- D. isotretinoin
Correct answer: D
Rationale: The correct answer is D, isotretinoin. Isotretinoin is a medication commonly used to treat severe acne, but it is a potent teratogen, meaning it can cause severe birth defects if taken during pregnancy. Aspirin (choice A) is not a widely used potent teratogen. Diethylstilbestrol (DES) (choice B) was a known teratogen, but it is not currently widely used. Thalidomide (choice C) was another historical teratogen, but it is also not currently widely used. Therefore, isotretinoin is the most relevant answer as it is a commonly used medication that poses a high risk of birth defects if used during pregnancy.
3. An ovum bursts from one of a woman's two __________ and is drawn into one of two __________.
- A. ovaries; testes
- B. fallopian tubes; ovaries
- C. corpus luteum; fallopian tubes
- D. ovaries; fallopian tubes Answer: D Page Ref: 76 Skill Level: Remember Topic: Prenatal Development Difficulty Level: Easy
Correct answer: D
Rationale: An ovum bursts from one of a woman's two ovaries and is drawn into one of two fallopian tubes. This is a correct description of the process of ovulation and fertilization in human reproductive anatomy. The ovaries are responsible for producing and releasing eggs, while the fallopian tubes provide a pathway for the egg to travel to the uterus for potential fertilization.
4. According to Jean Piaget, what is the balance between internal structures and information that children encounter in their everyday worlds?
- A. imitation
- B. adaptation
- C. cognition
- D. equilibrium
Correct answer: D
Rationale: According to Jean Piaget, equilibrium is the balance between what children already know (internal structures) and the new information they encounter. Imitation (choice A) is not directly related to this concept. Adaptation (choice B) involves adjusting to new information and is part of Piaget's theory, but it does not specifically refer to the balance between internal structures and external information. Cognition (choice C) is a broader term that encompasses mental processes, including thinking, learning, and problem-solving, but it is not specifically about the balance between internal structures and external information as equilibrium is.
5. The term teratogen refers to __________.
- A. any environmental agent that causes damage during the prenatal period
- B. a limited time span during which a part of the body is biologically prepared to develop rapidly
- C. a rapid period of prenatal neurological development
- D. a synthetic hormone used to prevent miscarriage
Correct answer: A
Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.
